[georss] which version?

[Carl Reed OGC Account]

Just a bit more information in addition to what Andrew and Raj already provided.

The W3C vocabulary (geo) was published in January 2003. The "first" version of GeoRSS was published in January 2006. The W3C geo is a basic RDF vocabulary that provides the Semantic Web community with a namespace for representing lat(itude), long(itude) and other information about spatially-located things, using WGS84 as a reference datum. It supports only the encoding of point geometries.

GeoRSS Simple and GeoRRS GML (www.georss.org) provides a much richer and extensible vocabulary for encoding location into RSS feeds. If I were implementing an RSS reader, I would at the very least support GeoRSS Simple. 

Just one other point: The GeoRSS Simple and GML encodings are consistent (aligned) with how geometry is defined in the ISO 19107 standard, OGC GML and other OGC standards, the OMA MLP standard, various Internet draft standards (PIDF-LO, e.g.), the use of geometry in the IEEE 1451 standard, and soon a variety of standards from OASIS.

Regards

Carl

  Subject: [georss] which version?


  Hello All,

  I have a few kind of related questions... if any one could help, i would appreciate it...



  I was wondering, out of the W3C version and the GML version, which version of georss is more popular at the present time with readers that can understand georss?  

  for most GeoRSS readers, do they understand both?  That is, if one version is used, will it mean some readers will not understand it?

  And, on my site i will have a mix of some news articles that have geometry, and some that don't, do you think it would be best to have 2 separate RSS links?  A GeoRSS link, exclusively for items with geometry, and then an RSS link for everything?
